Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672480, here are decompositions:

73 + 8672407 = 8672480
127 + 8672353 = 8672480
241 + 8672239 = 8672480
277 + 8672203 = 8672480
379 + 8672101 = 8672480
433 + 8672047 = 8672480
499 + 8671981 = 8672480
643 + 8671837 = 8672480

Showing the first eight; more decompositions exist.
